Here you start to salivate and secrete some gastric fluid into your stomach.The gastric phase of digestive secretion happens after you swallow food, when protein stimulates the release of stomach acid and digestive enzymes.In the intestinal phase, the presence of food particles activates hormones that, in turn, cause the secretion of bicarbonate buffer, bile and additional digestive enzymes.uring the gastric phase of digestion, the muscles of your stomach wall flex to help mix together food particles, gastric juice and pepsin before the food moves on to your small intestine.
